Valve Implantation

Transcatheter aortic valve implantation (TAVI) and endovascular aortic repair (EVAR) are increasingly being used as therapeutic options for patients with severe aortic stenosis who are ineligible for surgery and who have aortic aneurysm with suitable anatomical features. These procedures can be associated with severe complications, especially related to vascular access and the use of a large introducer sheath (from 18 to 24 French [Fr]). In this article we describe possible vascular complications emerging during TAVI and EVAR and their appropriate management, beginning with patient selection, the correct way to perform vessel puncture and the use of a vascular closure device, up to the recently proposed cross-over technique, which is thought to minimise the risk of dangerous consequences of vascular damage.

Abstract Background Increasing number of symptomatic patients with severe aortic stenosis is treated with transcatheter aortic valve implantation (TAVI). Stroke is one of the most serious complications of TAVI, and the majority of cerebral events in patients undergoing TAVI have an embolic origin. Case summary A 90-year-old female underwent trans-femoral TAVI for symptomatic severe aortic stenosis. Just before the implantation of the transcatheter heart valve (THV), transoesophageal echocardiography (TOE) showed a mobile, high-echoic mass attached to the THV, which gradually enlarged to 26 mm, then spontaneously detached from the THV and flowed up the ascending aorta, disappearing from the TOE field of. After the procedure, the patient presented with ischaemic stroke. The patient’s stroke was thought to have resulted from the embolism migrating to the distal cerebral arteries. Discussion The detailed images acquired with TOE during TAVI enabled the prompt identification of the unusual intracardiac mass.
